(0) CpxIntTrs (1) Loat Proof [FINISHED, 207 ms] (2) BOUNDS(INF, INF) ---------------------------------------- (0) Obligation: Complexity Int TRS consisting of the following rules: f1(A, B, C, D, E, F, G, H) -> Com_1(f1(A, B, I, J, K, F, G, H)) :|: B >= 1 + A f1(A, B, C, D, E, F, G, H) -> Com_1(f300(A, B, I, J, E, K, G, H)) :|: A >= B f2(A, B, C, D, E, F, G, H) -> Com_1(f1(A, B, C, D, E, F, I, J)) :|: TRUE The start-symbols are:[f2_8] ---------------------------------------- (1) Loat Proof (FINISHED) ### Pre-processing the ITS problem ### Initial linear ITS problem Start location: f2 0: f1 -> f1 : C'=free_2, D'=free, E'=free_1, [ A>=1+B ], cost: 1 1: f1 -> f300 : C'=free_5, D'=free_3, F'=free_4, [ B>=A ], cost: 1 2: f2 -> f1 : G'=free_7, H'=free_6, [], cost: 1 Checking for constant complexity: The following rule is satisfiable with cost >= 1, yielding constant complexity: 2: f2 -> f1 : G'=free_7, H'=free_6, [], cost: 1 Removed unreachable and leaf rules: Start location: f2 0: f1 -> f1 : C'=free_2, D'=free, E'=free_1, [ A>=1+B ], cost: 1 2: f2 -> f1 : G'=free_7, H'=free_6, [], cost: 1 ### Simplification by acceleration and chaining ### Accelerating simple loops of location 0. Accelerating the following rules: 0: f1 -> f1 : C'=free_2, D'=free, E'=free_1, [ A>=1+B ], cost: 1 Accelerated rule 0 with NONTERM, yielding the new rule 3. Removing the simple loops: 0. Accelerated all simple loops using metering functions (where possible): Start location: f2 3: f1 -> [3] : [ A>=1+B ], cost: NONTERM 2: f2 -> f1 : G'=free_7, H'=free_6, [], cost: 1 Chained accelerated rules (with incoming rules): Start location: f2 2: f2 -> f1 : G'=free_7, H'=free_6, [], cost: 1 4: f2 -> [3] : G'=free_7, H'=free_6, [ A>=1+B ], cost: NONTERM Removed unreachable locations (and leaf rules with constant cost): Start location: f2 4: f2 -> [3] : G'=free_7, H'=free_6, [ A>=1+B ], cost: NONTERM ### Computing asymptotic complexity ### Fully simplified ITS problem Start location: f2 4: f2 -> [3] : G'=free_7, H'=free_6, [ A>=1+B ], cost: NONTERM Computing asymptotic complexity for rule 4 Guard is satisfiable, yielding nontermination Resulting cost NONTERM has complexity: Nonterm Found new complexity Nonterm.
